Reversible watermarking technique using small-world cellular neural network
Kazuya Tsuruta, Yoshifumi Nishio · 2006
Recently, the authors have proposed small-world cellular neural network (SWCNN), which is constructed by introducing some random couplings between cells of the original Chua-Yang CNN and we have reported some basic results using the concept of SWCNN. In this paper, we propose an image watermarking technique that the connection topology of SWCNN plays the role of "key" and investigate its features.
